ENTERTAINMENT AT RIVERFEST:

Music, cornhole, rubber ducks and ? zombies? The fun to be had during this year's 2013 Cincinnati Bell/WEBN Fireworks and P&G Riverfest gets a little wackier with the addition of the Dent Schoolhouse/ WEBN Zombie Walk. Get your zombie on and gather at Sawyer Point's P&G Great Lawn from 5-5:30 p.m. Sunday in advance of the 5:30 p.m. walk (err, stagger?). But if zombies aren't your thing, never fear; Riverfest also includes:

? Cornhole tournaments: An American Cornhole Organization National Qualifier Tournament, 2-5 p.m. Sunday ($25 per team in advance; $40 at the event if space is available) and Luck of the Draw tournaments, noon-4 p.m. Sunday ($5 per player buy-in for each tournament), plus a world record long toss challenge, noon-7:30 p.m. Sunday ($2 per attempt; $20 to play all day in all three game challenges). www.americancornhole.com

? Skate park demonstrations (1, 4 p.m. and 6 p.m. Sunday)

? The annual Rubber Duck Regatta (3 p.m. Sunday), when as many as 200,000 ducks will be dropped from the Purple People Bridge into for the race on the Ohio River. (Ducks are $5. Prizes include a Honda Civic Sedan LX - and possibly $1 million if the winning duck is the "Kemba Million Dollar Duck" - a $100 Kroger gift card per week for a year and $500 cash. Proceeds support the Freestore Foodbank.) www.rubberduckregatta.org or freestorefoodbank.org.

?

Now in its 22nd season, the haunted attraction is built on an actual wrecked steamboat located on Riverboat Row in Newport, in front of Newport on the Levee. It opens again Sept. 13 and 14 before regular hours begin Sept. 20. Tickets then are $13 on Wednesdays and $18 Thursday-Sunday. www.USSNightmare.com.

? A blanket (Blankets can be placed on Serpentine Wall after 6 a.m. on Saturday; the park officially opens at 6 a.m. Sunday.)
